Instrument Panel, Gauges and Warning Indicators: Testing and Inspection

INSTRUMENT CLUSTER

INSPECTION

SPEEDOMETER
1. Adjust the pressure of the tires to the specified level.




2. Drive the vehicle onto a speedometer tester. Use wheel chocks as appropriate.







3. Check if the speedometer indicator range is within the standard values.

CAUTION: Do not operate the clutch suddenly or increase/decrease speed rapidly while testing.

NOTE: Tire wear and tire over or under inflation will increase the indication error.

TACHOMETER
1. Connect the scan tool to the diagnostic link connector or install a tachometer.




2. With the engine started, compare the readings of the tester with that of the tachometer. Replace the tachometer if the tolerance is exceeded.

CAUTION:
- Reversing the connections of the tachometer will damage the transistor and diodes inside.
- When removing or installing the tachometer, be careful not to drop it or subject it to severe shock.

FUEL GAUGE
1. Disconnect the fuel sender connector from the fuel sender.
2. Connect a 3.4 wattages, 12 V test bulb to terminals 1 and 3 on the wire harness side connector.




3. Turn the ignition switch to the ON, and then check that the bulb lights up and the fuel gauge needle moves to full.
